REGEX in blacklist doesn't work as intended


Hello folks,


I encountered a problem when trying to filter events from WinEventLog and EventCode 4662.  When I use the next regex in a tester or in a SPL with a data set unfiltered, it works fine. But using it in a blacklist only allows a fraction of the messages when "Default Property Set" is in the first row after Properties.


blacklist9 = EventCode="4662" Message="(Tipo\sde\sobjeto:(?!\s*groupPolicyContainer))[\s\S]*(Propiedades:(?![\s\S]*Default Property Set))"

I tried some changes to the regex but I do not find a solution for this. Thanks for your time.

@osakachan  Can you check are you following allowed regex its little different from PCRE- inputs.conf - Splunk Documentation

Have you tried using erex to help build your regex? It's a hidden gem, and extremely useful.


An upvote would be appreciated and Accept Solution if it helps!
